    <p>I'm trying to write a select box in Ember, based on a Rails back end. When editing the model Recipes, I want to be able to select from a list of Sources in a dropdown. Right now in Ember I'm getting the message "The value that #each loops over must be an Array. You passed App.Sources" as a result of the following code.</p> <p>I have tested the REST api and it is providing the response for Recipes and Sources both properly.</p> <p>I'm new to Embers (and Javascript too, actually!) and I feel like I'm missing something basic. Thank you for any tips.</p> <p>Here's my JS:</p> <pre><code>App.RecipeEditController = Ember.ObjectController.extend({ needs: ['sources'], selectedSource: null, actions: { save: function() { var recipe = this.get('model'); // this will tell Ember-Data to save/persist the new record recipe.save(); // then transition to the current recipe this.transitionToRoute('recipe', recipe); } } }); App.RecipesRoute = Ember.Route.extend({ model: function() { return this.store.find('recipe'); }, setupController: function(controller, model) { this._super(controller, model); this.controllerFor('sources').set('content', this.store.find('source')); } }); App.SourcesRoute = Ember.Route.extend({ model: function() { return this.store.find('source'); } }); DS.RESTAdapter.reopen({ namespace: "api/v1" }); App.Recipe = DS.Model.extend({ title: DS.attr('string'), url: DS.attr('string'), rating: DS.attr('number'), source: DS.belongsTo('source', { async: true }), page_number: DS.attr('number'), want_to_make: DS.attr('boolean'), favorite: DS.attr('boolean') }); App.Source = DS.Model.extend({ title: DS.attr('string'), authorLast: DS.attr('string'), recipes: DS.hasMany('recipe', { async: true }) }); App.Router.map(function() { return this.resource("recipes"); }); App.Router.map(function() { return this.resource("recipe", { path: "recipes/:recipe_id" }); }); App.Router.map(function() { return this.resource("recipeEdit", { path: "recipes/:recipe_id/edit" }); }); App.Store = DS.Store.extend({ revision: 11, adapter: DS.RESTAdapter }); </code></pre> <p>And here's the view:</p> <pre><code>{{view Ember.Select contentBinding="controllers.sources.content" optionLabelPath="content.title" optionValuePath="content.id"}} </code></pre> <p>UPDATE And here's the JSON:</p> <pre><code>{ "recipes": [ { "id": 3, "title": "Did this make it through?", "url": "www.hellyeahitdid.com/high-five/", "rating": null, "source_id": null, "page_number": null, "want_to_make": false, "favorite": false }, { "id": 1, "title": "Here's another totally crazy one for ya", "url": "http://www.example.com/recipe/1", "rating": null, "source_id": null, "page_number": null, "want_to_make": false, "favorite": false }, { "id": 2, "title": "A Sample Recipe", "url": "http://www.example.com/recipe/1", "rating": null, "source_id": null, "page_number": null, "want_to_make": false, "favorite": false } ] } { "sources": [ { "id": 1, "title": "Joy of Cooking", "author_last": null }, { "id": 2, "title": "Everyday Food", "author_last": null } ] } </code></pre>

    2. COThanks for your help @kingpin2k. It does work for Recipes---I can see an index and I can show a single record. However I haven't set up any views for the Sources. I'll see if creating those helps me uncover the problem. Another piece of diagnostic info: in my Rails server log there's no sign that Ember is hitting the route or controller for Source. No 500, no thing. So I'm thinking I'm doing something wrong in Ember. Thanks for the cleaner Router as well.

    3. CORoutes define how ember should handle a route from the url. The model hook is only hit when you visit that route. Are you wanting to access sources from the recipes route?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
